Systems and methods for creating hair transplantation procedure sites
Methods and systems are provided for determining the location of procedure sites, for example hair implantation sites, the method and systems enabling a natural looking randomness to be maintained to achieve a desired density while avoiding previously created procedure sites and existing features.
1. A method for automatically selecting a location of a procedure site on a patient, the method comprising:
proposing a candidate procedure site on a patient;
identifying a follicular unit that exists within a certain distance from the candidate procedure site;
automatically determining, using image processing, if the existing follicular unit is terminal or non-terminal; and
selecting from available options of:
1) if the existing follicular unit is determined to be non-terminal, proceeding with procedure site making at the proposed candidate procedure site; and
2) if the existing follicular unit is determined to be terminal, proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit.
2. The method of claim 1 , wherein a non-terminal follicular unit is a vellus follicular nit, a dying follicular unit, or a non-regenerating follicular unit.
3. The method of claim 1 , wherein proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit comprises offsetting the location of the candidate procedure site in one or more predetermined directions.
4. The method of claim 1 , wherein proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit comprises offsetting the location of the proposed candidate procedure site by a predetermined distance.
5. The method of claim 1 , wherein the proposed candidate procedure site comprises a follicular unit implantation site.
6. The method of claim 1 , wherein identifying a follicular unit that exists within a certain distance from the candidate procedure site comprises identifying a follicular unit that exists within 2 millimeters from the candidate procedure site.
7. A method of selecting a location of a procedure site, the method comprising:
proposing a candidate procedure site on a patient;
identifying a follicular unit that exists within a certain distance from the candidate procedure site;
automatically classifying, using image processing, the existing follicular unit as terminal or non-terminal; and
selecting from available options of:
1) if the existing follicular unit is classified as non-terminal, proceeding with procedure site making at the proposed candidate procedure site; and
2) if the existing follicular unit is classified as terminal, proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit.
8. The method of claim 7 , wherein a non-terminal follicular unit is a vellus follicular nit, a dying follicular unit, or a non-regenerating follicular unit.
9. The method of claim 7 , wherein proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit comprises offsetting the location of the candidate procedure site in one or more predetermined directions.
10. The method of claim 7 , wherein proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit comprises offsetting the location of the proposed candidate procedure site by a predetermined distance.
11. The method of claim 7 , wherein the proposed candidate procedure site comprises a follicular unit implantation site.
12. The method of claim 7 , wherein identifying a follicular unit that exists within a certain distance from the candidate procedure site comprises identifying a follicular unit that exists within 2 millimeters from the candidate procedure site.
13. A system for selecting a location of a procedure site, the system comprising:
a user interface including a user input device;
at least one non-transitory storage medium storing instructions, and
one or more modules for executing operations on image data, the one or more modules comprising instructions for:
proposing a candidate procedure site on a patient;
identifying a follicular unit that exists within a certain distance from the candidate procedure site;
automatically determining, using image processing, if the existing follicular unit is terminal or non-terminal; and
selecting from available options of:
1) if the existing follicular unit is determined to be non-terminal, proceeding with procedure site making at the proposed candidate procedure site; and
2) if the existing follicular unit is determined to be terminal, proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit.
14. The system of claim 13 , wherein a non-terminal follicular unit is a vellus follicular nit, a dying follicular unit, or a non-regenerating follicular unit.
15. The system of claim 13 , wherein proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit comprises offsetting the location of the candidate procedure site in one or more predetermined directions.
16. The system of claim 13 , wherein proposing another candidate procedure site such that the candidate procedure site is not too close to the existing follicular unit comprises offsetting the location of the proposed candidate procedure site by a predetermined distance.
17. The system of claim 13 , wherein the proposed candidate procedure site comprises a follicular unit implantation site.
18. The system of claim 13 , wherein identifying a follicular unit that exists within a certain distance from the candidate procedure site comprises identifying a follicular unit that exists within 2 millimeters from the candidate procedure site.
